leak proof, package secure against unintentional discharge of contents, and, in a preferred embodiment of the invention, a package wherein the container in which the liquid is stored is additionally protected against injury by an outer casing and is firmly held within said casing against destructive displacement, rattling, and the like. The present invention further contemplates, in its most refined form, the provision of a. pack-. age which is composed of a container proper and a surrounding casing which is. so assembled around the container that access to the charging opening cannot be had for refilling purposes except by destruction or ermanent injury of the casing. Other ob ects of the invention and of details associated therewith will appear from the following specification.

The present invention is illustrated inconnection with a package intended to contain a hydrofluoric acid containing fluid such as is used in laundry practice for the local treatment of spots and discolorations. Such liquid, on coming into contact with the skin,

, produces verypainful and injurious burns occasionally, unless promptly treated, penetrating to the bone. The acid, when coming in contact with a nail, will easily cause the loss of the nail. Instances have occurred where persons have been obliged to undergo hospital treatment for periods of several months before an injury resulting from contact with such fluid was healed. It is accordingly of the utmost importance that a package of this type of fluid should be absolutely leak-proof and otherwise so arrangedthat the operator in the use of the fluid will be able to control it without any reasonable likelihood of having the liquid make even accidental contact with his hand. In order to accomplish these objects the container proper. constructed of a material such as hard rubber or other rigid material which resists attack on the part of the contained fluid, is shaped and dimensioned to beheld in one hand and to be manipulated by' that hand like a tool. A cylindrical chamber adapted to contain approximately fiveounces or so of the fluid represents a typical size and shape. -The liquid emission part of the container is given the form of an extended tapered nozzle apertured for communication with the interior of the container so that the fingers of the operator, being placed about the body of the container itself, will always be remote from the point of discharge of liquid from the nozzle. The nozzle element is a unitary body comprising five functional elements, (1) a threaded section adapted to cooperate with threads'associated with an aperture extending through a wall of the container proper; (2) a flange adapted to cooperate with a washer seated between said flange and that part of the casing theouter edge of the threaded part the container is provided with a sunken seat to receive the washer or gasket and of such depth that when the washer is fully compressed in place the outside face, of the flange of the nozzle section is approximately flush with the outer surface of thecontainer. A cap, preferably provided with exterior irregularities to enable it to be tightened or loosened, cooperates with the fourth above identified part of the nozzle section in such a way that when the cap is fully seated its surface at the open end will make a continuous contact with the outer surface of the third above specified elements of the nozzle section so as to prevent the escape of fluid through this joint. The inner extent of the cap is approximately the same as the length of the nozzle so that when the cap is in place it will abut against the aperture at the extreme end of the nozzle and keep it closed.

The accompanying drawing illustrates by way of example a preferred embodiment of the invention. In said drawing Fig. 1 is a vertical view partly of a cross-section of a package constructed in accordance with the,

present'invention, the same being shown in assembled condition justprior to the sealing in of the casing, the container being in position within the casing and having its nozzle screwed thereon, the bottom of the casing being applied thereto in the form of a blank prior to its permanent attachment to the ody of the casing. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a view in elevation partly in section, showing the cap in position on the nozzle and showing also the bottom of the casing attached to the cylindrical body thereof. Fig. 4 is a top plan view of ig. 3. Fig. 5 is a top view of the empty casing, and Fig. 6 is a sectional view representing a modification of the tip and cap structure of Fig. 3.

In the drawing 10 indicates a container which may beof cylindrical form, made of suitable material such as hard rubber, a resinous, molded composition, or other nonmetallic substance non-attachable by the fluid. The container is provided with a counter-sunk portion continued as a threaded opening 11 to receive the threaded end of a nozzle 12, made of similar material. The nozzle 12is provided with a fixed collar 13 ;between which and the bottom of the counter-sunk portion of the opening a washer 14 of rubber or equivalent substance is adapted to be placed to insure a tight joint between the nozzle and the container. The depth of the counter-sinking and the thickness of the washer 14 and collar 13 are preferably so related that when the nozzle is screwed down tight upon the container. the top of the collar is flush with the top surface of the container.

The nozzle is provided with a fixed, preferably integral non-circular or angular portion 15 illustrated as hexagonal in contour. The portion 15, whatever its contour, should preferably have a maximum diameter slightly smaller than that of the collar 13. The object of the portion 15 is to provide engaging means for a wrench or tool by means of which the nozzle portion of the structure may be more tightly seated upon the washer 14 than can be accomplished by hand. The washer 14, made of rubber or other compressible material not attackable by the fluid. is by such means'held so firmly in position that it is for practical purposes impossible to loosen the connection between the nozzle section and the container by hand or by any manipulations of the assembled device in um but only by special application of ato l is provided with a discharge duct 16 which is so small as to make it extremely difiicult if not ractically impossible to have it emit more t an the desired amount of fluid in use or to refill the container through said duct. The nozzle is'also provided with a threaded portion 17 shown as located directly above the angular portion 15 for receiving a correspondingly threaded cap 18. The nozzle and cap are preferably made of the same material as the container and like the latter ma be manufactured by molding. The cap s own in Fig. 3 is provided with a cushion orpacking 19 of soft rubber which operates to close the duct 16 and to prevent injury to the discharge end of the nozzle when the cap is in osition thereon as illustrated in Fig. 3. t is, however, preferred to incorporate in the nozzle and in the cap soft rubber tips 18a and 12a as illustrated in Fig. 6, the advantage of this construction being, first, that the soft rubber tip on the nozzle supplies a much better point with which to spread the chemical fluid over the stain on the fabric and is not so likely to injure the fabric as when a hard rubber edge bounds the mouth of the duct and, second, that with a soft/rubber tip on the cap as well as on the nozzle, the cap can be drawn firmly upon the nozzle and make a sure seal without requiring an extra washer with the tip.

The container is positioned within the easing 20 whose internal diameter is preferably equal to the external diameter of the container. so as to provide a snug fit. The container with the nozzle in position thereon is inserted into the casing 20 through the open bottom of the latter, as illustrated in Fig. 1, and the nozzle and angular portion 15 are passed through an opening 21 in the metal coverplate 22 which is fixed to the tubular body of the casing, the opening 21 having the same outline as the angular portion or being at least so configured that relative rotary movement between the angular portion 15 and the metal plate 22 is prevented. When the container is in position within the casing, the top surface of the collar 13 bears against the under surface of the cover plate 22. As shown in Figs. 1 and 3, the top of the container ,or at least the portion thereof adjoining the collar 13 may be made fiat in order that it may seat itself snugly against the top the nozzle and a bottom plate 25 in the form of a blank is positioned against the bottom of the casingand firmly attached thereto in any suitable manner asfor instance by clamping the bottom edge of the casing within the turned-over ed%hof the blank 25 as shown at 24 in Fig. 3. e bottom section 23 of the casing may be provided with a raised portion 25 which, when the bottom plate 23 is fitted against the lower edge of the casing, engages the bottom of the container. The cover 22 may be similarly associated with the casing, but is permanently crimped and clamped to the casing before the container is introduced into the casing. As vwill be seen in Fig. 1, the container is slightly longer than the normal distance between the top and bottom plates 22, 23, so that as the bottom plate is clam ed to the casing, the top plate at least will slightly flexed in an outward direction, so that the container itself is held under resilient pressure within the casing.

The casing is preferably made of cardboard or the like and if desired, the metallic plates thereof may be in the form of screw capsin which event the casing may be provided with similarly threaded metallic bands at its edges. To make the casing non-operable,when the screw cap modificationis used. the lower cap and its band may be soldered together or the threaded portions may, after proper association with eachother, be pricked to prevent rotation of the cap or caps or otherwise physically deformed to supply an efiective seal which wi l necessitate the destruction of the seal or of the casing'before access can be had to the container.

The outer surface of the casing may con- 'tain any suitable printed mattcnadhesively applied thereto such as labels bearing trade marks the name of the manufacturer, directions for use or other similar matter.- The use of a cardboard casing is particularly advantageous when the container is required to be made of hard rubber or equivalent substance since labels do not readily adhere to material such as hard rubber while they will remain in almost permanent adhesion upon a cardboard surface. v

It will be evident that the angular portion 15 in cooperation with the correspondingly.

shaped screwing rotation of the container within the casing and thus serves to hold the container in fixed position. The nozzle 12- cannot be removed when the container within the casing and it is consequently practically impossib anyone to refill the container without first so damaging the casing that it cannot be used again. The improved package accordingly renders it extremely diflicult if not impossiwalls of the opening 21 prevents un-' of the nozzle 12 and also prevents being made of card- 19 .ioning means reducing shockssufl'ered by the container when the package is shipped or dropped or otherwise subjected to rough usage. The improved package is extremely simple in construction and can be manufactured at low cost. The package is so reliable that notwithstanding its extremely destructive and corrosive contents it can be sent through the mails by being enclosed in an ordinary mailing tube.

It will be seen from the foregoing description that the invention provi es a package or carboy-for corrosive llquids or other dangerous materials comprising a casing and a container substantially completely encased thereby, the container being provided ,with a nozzle rojecting through the top 'of the casing an the parts so constructed, dimens ioned and interrelated that the container is held against movement withinthe casing and that further, in the particular form of the invention illustrated in the drawing, a package is provided wherein a container is enclosed by a completely sealed casing in such a manner that access to the container cannot be had without destruction of\ the casing. c

Variations from the specific form of the invention illustrated may be resorted to within the scope of the appended claims without departing from. the spirit of the invention. For example, the container 10 may be provided with a separate charging opening at one side of the nozzle, such opening being closed by a plug or other suitable means, in which case the nozzle 12 may be molded integrally with the body of the container, the plug lying below the top plate 22 when the container and easing are assembled so as not to be reachable for refilling purposes withceive a washer, a threaded aperture surrounded by said seat and dimensioned for conven-- ientfilling of the chamber therethrough, a

washenfa nozzle section of relatively nonbreakable material, proof against corrosive attack of the liquid contained in the chamber,

apertured to permit passage of liquid from the chamber and having an exit duct of such small calibre as to prevent free flow of liqui d therethrough, said nozzle section having uid-tight position with at one end thereof a tapered. nozzle extending to a point relatively remotefrom the apertured wall of the chamber and at the other end of-thenozzle section a screwthreaded 1 portion adapted to engage the threads of the ciated with said nozzle section adapted for engagement by a tightening tool, a cap-engaging and seating portion associated with said nozzle section, and a cap adapted .to cooperate with the cap-engaging portion of the nozzle section and to be held thereby in liquid-tight position with reference to any liquid which might pass through the nozzle during the time the cap is in place.
